Fig. 4From: Comparing dental plaque microbiome diversity of extrinsic black stain in the primary dentition using Illumina MiSeq sequencing techniqueBacterial distribution of the top 100 most abundant genera among the 20 samples. Heat map analysis was performed based on the hierarchical clustering solution (Bray-Curtis) distance metric. Columns represent the sample ID, and rows represent the predominant bacterial genera. Variables of clustering are presented on the vertical axis. The relative values for bacterial genera are indicated by colour intensity, the legend is indicated at the top right corner.
